Living in the 21st century, you have heard the word smart device being thrown around left and right. Smart Locks, smart mobile device, smart lighting systems, smart thermostats, smart watches, smart TVs even Smart refrigerators are now available on the market. They have now become the top smart home devices on homeowner’s Wishlist.

What is a Smart Device?

A smart device is any device that is intelligent enough to connect and interact with the person using it as well as other smart devices connected around it.

A smart device is made intelligent with advanced computing. For example, AI and machine learning, coming together to form the internet of things (IoT). SMART itself stands for Self-monitoring, Analysis, and Reporting Technology.

What is IoT?

multiple devices

IoT stands for Internet of Things, and it’s a term used to describe the growing trend of everyday objects being connected to the internet. This can include anything from refrigerators to cars to lightbulbs. The goal of IoT is to make our lives easier by allowing us to control these objects remotely and collect data about them.


Most notable examples of smart devices that are around us include smart TVs that most of us now have that connect to the internet and allow access to Netflix and Youtube. The mobile phones that most of us have in our pockets and have become a major part of our lives are smart. Smart cars are now being introduced, having autopilot and GPS systems etc. Smart thermostats, smart locks, smart watches, smart refrigerators, smart doorbells, and even smart refrigerators are now available and have all become a major part of our lives.


Here are some key features of the best smart home devices and most common smart devices:

Autonomy, using available information to make decisions and recommendations

The ability of a device to perform a task without the direct command of its user, like, when your mobile smart device (your phone) uses your location to make a suggestion.


It is the ability of a device to connect to a data network. Network connectivity is a very crucial aspect of a smart device because of which it becomes a part of the internet of things. Without it, there is no point in the whole Autonomy concept.

Context-Aware electronic device

The ability of a system to gather information from its surrounding at a particular time and adapt accordingly at that particular moment is called context-awareness.

The source for this data might be cameras, microphones, radar and LIDAR sensors. The information is processed by computing intelligence.


A smart device does not necessarily have to interact with human beings directly. When you are thinking about user interaction, most of us would think about smartphones, smart TVs, smart watches, etc. But there is much more to that. A smart device can also be any other devices that have direct or indirect interaction with a human being. For example, a weather probe collects weather data and transmits it to the Internet of Things, which is later utilized by human beings. Therefore, indirectly interacting with people.


Portability is not a major factor, but in some instances, you might require a device to be portable. For instance, Is a mobile smart device? Yes. But is a smart surveillance camera portable. No. Well, strictly speaking, it is not portable after the installation, but before that, it was (wise guy?)

But the major factors are the first three being context awareness, autonomy and connectivity.

When is a device a smart device?

Smart devices are able to incorporate functions like sensing, actuation. They also control and analyze situations and make decisions based on the information received through these functions. When a device is able to do all of that it is called a SMART device.

Are Computers an IoT device?

An IoT device is a device that has a sensor attached to it and can connect with other devices through the internet connection. A computer or a laptop is definitely an IoT device as it extends internet connectivity beyond standard devices, i.e., laptops, and computers, to non-internet devices and everyday physical objects. So yes, a computer, a laptop or a mobile phone are all IoT devices.

How are the most common smart devices used today?

IoT has revolutionized the world in every aspect of life. The main purpose of IoT is to access and operate with minimum human intervention. This will make life easier and easier day by day for us. Here are some daily life applications of smart devices:

Wearable Health Monitors:

Wearable health monitors include smart clothes, medical wearables, and smart wristwear. They consistently provide you with information about your health. They track your activities such as pulse rate, breathing rate, and heart rate. This data is available to be used by your doctors later on. Furthermore, they can raise the alarm in case something severe happens, for example, in case of an asthma attack or seizures.

Disaster Management:

Take a situation, for example, forest fires happen a lot these days and spread far faster than one might expect. We can install smart sensors around the boundaries of forests. They will constantly monitor the temperature and carbon content of the air. In case of fire, an alert would be sent to forest control authorities, and timely action will save us from a disaster that could otherwise cause huge chaos.

Biometric Security System:

Biometric security systems make use of fingerprints, eyes scan, voice scans and face recognition. To record someone’s presence or to allow access to a secured room with documents on secured databases. The data is usually stored in the host computer because the smart devices interact with each other. They have access to your data and thus are able to recognize your face, voice, fingerprint or to associate you with information you enter.

Smart Cars:

IoT allows cars to communicate with each other to exchange information such as speed as well as you the driver. For example, when the GPS finds your shortest route to your desired location. These cars also let you know if the car requires maintenance or repair. Basically, there are two types of interactions that a smart car will do.

It will provide a detailed analysis of the car itself and let you know about the status of your car

It will interact with other cars and surroundings through sensors and avoid unnecessary clipping and collisions. This is a very high bandwidth exchange.


Farmers today are facing a lot of problems due to our exploitation of the earth and the atmosphere, with climate change being a major challenge. Here’s how IoT helps you if you are a farmer.

A number of sensors monitor the moisture of the soil. If the moisture level is below the mark, it automatically turns on the irrigation pump.

It would be best if you recovered the soil’s nutrients before farming a new crop. They can be examined and analyzed by the IoT that will let you know what you have to do.

It senses the requirements of fertilizers and other farming needs for you.

Lighting Systems:

Smart lighting systems are now being installed in homes that are integrated to interact with you and prioritize your comfort. Automated lights turn on by detecting just the presence of you. They may also be programmed to listen to your voice commands. Alter themselves according to the mood of the environment and also save energy according to your budget to help you with your energy bills.

Shopping Malls:

Have you ever seen a shopkeeper using a barcode machine on the items you have purchased to find their price? Well, the barcode machine is connected to a host computer which is then also connected to a billing machine. All the information from the barcode of a product is sent to the host computer and then to the billing machine, which then prints out the overall bill. This is the Internet of things


smart home devices

A smart home is a setup where all your appliances and devices are connected to each other. They’re also connected to the internet and are readily accessible on a mobile device having an internet connection. An automated home might have smart lighting, energy management, remote access and expansion. You will be able to have access to lighting, temperature, your door locks, television, thermostat, refrigerator and a home theatre. All of which are controlled by a single central device like your mobile phone, tablet, or a home assistant like Alexa. Some smart homes are self learning as well and can do the scheduling of your tasks themselves.

Another feature that a smart home system can have is a smart home security system. Many of them can sense motion while the owner is away and automatically alerts the police in case of burglary. This can be a very expensive and affordable at the same time to setup. It varies based on the homeowner’s need, but there are options for any budget.

Final thoughts

The IoT, and smart devices have revolutionized the world. Smart electronic appliances now have started to take over activities that once a normal individual would have to do themselves. The device-to-user interaction has enabled the technology to solve almost all the daily life problems of a person. With the invention of smart lighting, smart TVs automated cars, and mobile smart devices you could just kick your feet up and relax while the internet of things does everything for you. You can be in any place and order your smart system to do daily life chores for you. All it takes, is a tap on your smartphone and other smart mobile devices connected to that smart system or Hub.
